About this study
The primary objective of this study is to assess the chances of increasing the number of antral follicles in ovarian tissue of patients with diminished ovarian reserve by activation of primordial follicles through ovarian cortex fragmentation. Secondary objectives are to assess potential association with the number of oocytes retrieved and pregnancy rates after IVF.

Questions about this trial
What is this clinical trial studying?
A study testing Ovarian tissue fragmentation in people with Diminished Ovarian Reserve, run by Podobnik Maternity and Gynecology Hospital at 1 site in Croatia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 28 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Croatia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Miro S Alebić, MD, PhD (+38516398001, msalebic@podobnik.hr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Antral follicle count (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2020; AzTrials last refreshed its copy on 7 Nov 2026.
